Definitions

  • the present invention relates to the manufacture of a granulated fertilizer, more particularly by treatment of vinasse.
  • vinasses come from wine distilleries, sugar refineries and beet and cane distilleries. Conveniently concentrated (dryness of 50 to 60% for example), it is possible to burn them in a boiler whose burners they supply, in a manner analogous to black liquor in paper mills, the minerals contained in vinasses being recovered at the base of the boiler hearth in the form of ashes in the molten state, as described in document EP-A-48,061. These ashes contain potassium salts which can be used as fertilizer and for this use it is advantageous to obtain them in the form of granules.
  • the object of the present invention is to allow the recovery of mineral matter from vinasses in the form of granules.
  • a more specific subject of the invention is a process for manufacturing a granulated fertilizer, by treatment of vinasses, consisting in incinerating vinasses suitably concentrated in a boiler of which they supply the burners and recovering, at the base of the boiler hearth , mineral matter in the form of ashes in the molten state and characterized in that a fluid is injected into said ashes to break the liquid stream and disperse it into droplets, and said droplets are simultaneously projected into a bath of '' a saturated solution of ash.
  • the jet injected into the liquid vein is preferably a jet of water vapor.
  • the vinasse liquor is acidified with sulfuric acid before admission to the burners.
  • the invention also relates to an installation for the manufacture of a granulated fertilizer by treatment of vinasses comprising a boiler with tubular walls comprising a hearth, at least one vinasse liquor burner disposed in the hearth, an intake of preheated air in the hearth and a chute arranged at the base of the hearth for discharging the mineral matter in the form of ashes in the molten state, and characterized in that it also comprises a granulator at the upper part of which opens said chute, and a steam injection nozzle opening at said upper part of the granulator to break the liquid stream of ash and disperse it into droplets.
  • the granulator advantageously comprises a quenching and granulation tank, partially filled with a saturated ash solution, a means for agitating said solution and the droplets which it receives, and a conveyor disposed along the inclined bottom wall of the tank to extract the granules formed therein.
  • the granulator further comprises an upward vertical tube for eliminating mist, and a downward vertical tube for discharging the granules.
  • the single figure is a schematic view representing the entire installation.
  • reference numeral 1 generally designates a boiler with tubular walls. These boilers include a hearth 2 and a vertical tube bundle 3 mounted between two cylinders, respectively lower 4 and upper 5. In the walls of the hearth 2 are mounted burners, such as 6, inclined downwards and with assisted spraying. These burners are suitable for burning the vinasses coming from a reactor 7 supplied with vinasses by the piping 8 and sulfuric acid by the piping 9. Intakes 10 of preheated air, in the form of nozzles for example, open into the hearth 2 just below the burners 6. These inlets surround the fireplace 2.
  • the steam produced leaves the upper balloon 5 through the piping 13 while part of the steam is withdrawn by the tubular 14 for the needs of the installation itself.
  • a first need is to supply the air heater 15 which in turn supplies the aforementioned intakes 10.
  • a second need consists in supplying a granulator which will be discussed more explicitly below.
  • This granulator is constituted by a quenching tank 17 partially filled with a solution saturated with ash.
  • the tank 17 is supplied with liquid ash by the chute 18 exiting from the lower part of the hearth 2.
  • the steam taken from the piping 14 feeds an injection nozzle 19 at the upper part of the granulator 16.
  • the jet of steam breaks the vein liquid leaving the chute 18, and disperses it into droplets which are projected into the tank 17.
  • Said tank has in cross section the shape of a V whose narrow bottom supports a conveyor chain 21 which raises the granules towards the upper part through the free surface of the liquid contained in the tank 17.
  • Acidification of vinasses with sulfuric acid is not imperative, but it has the advantage of enhancing the ash which represents about 20% of the dry matter.
  • the attack on potassium and sodium salts should only be by in order to avoid an excess of free acid which could corrode the boiler.
  • organic salts and carbonates are thus transformed into sulfates. These salts leave the base of the hearth 2 in the molten state as in the case of a black liquor boiler.
  • the stream of liquid exiting through the chute 18 is at a temperature of the order of 600 ° C. This temperature is a function of the proportion of potassium and sodium salts in said liquid vein.
  • the molten ash consists of sulfates or carbonates depending on whether or not a sulfuric acid reactor has been provided upstream of the burners 6 of the boiler.
  • the liquor sprayed in the burners 6 burns with the air heated to 150 ° C. passing through the inlet nozzles 10. Inside the granulator 16, the relative movement of the drops and of the saturated solution promotes the cooling of said drops. The temperature of the solution stabilizes around 100 ° C.
